EXTENSIBLE CHANDELIER.

SPECIFICATION forming part of Letters Patent No. 779,132, dated January 3, 1905. application filed May 6,1904. Serial No. 206,755.

To all whom, it warty concern/.-

Be it known that I, GEORGE VVHITLocK POND, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented new and useful Improvements in Extensible Chandeliers, of which the following is a specification.

This invention relates particularly to chandeliers for burning gas that are suspended from the ceiling and which are vertically adjustable by meansof a rod on which the chandelier slides, combined with jointed folding pipes which permit the sliding action referred to.

The object of the invention is to produce an improved chandelier of the kind stated, characterized particularly by improvement in the heads or fittings to which the ends of the jointed sections of the gas-pipes are attached and in a wedge-clamp used to hold the fixture at various heights. An improved joint is also shown between the gas-pipe sections referred to.

In the accompanying drawings, Figure 1 is an elevation of the chandelier folded. Fig. 2 is an elevation, partly in section, with the chandelier partly extended. Fig. 3 is a sec tion on the line 3 3 of Fig. 2. Fig. 4: is a detail in section of the elbow-joint between the pipe-sections. Fig. 5 is an elevation of the upper head or fitting. Fig. 6 is an elevation, partly in section, of the lower head.

Referring specifically to the drawings, 6 indicates an upper head or 'fitting which is screwed onto the gas-pipe at the ceiling. This head has two branches, each of which contains a stop-cock 7 8 is a guide and suspension rod which is screwed into and. depends from the head 6. This rod works through a hole in the lower head 9, so that the lower head is slidable up and down thereon. The upper and lower heads are connected by jointed pipe-sections 10 and 10, of which the former is the upper section, connected to the upper head 6, and the latter the lower section, connected to the lower head 9. These connections are by turning joints at 11, and the sections 10 and 10 are connected by turning joint 12. One of said joints, 12, is shown in detail in Fig. 4:,

the part 13 having a tapered pillar 14E, fitting in a recess or bore in the part 15 and held therein by a screw under which are washers, including a compressed vulcanizedrubber washer 17, which has the quality of expanding in the presence of oil or moisture, so that if any gas tends to escape the moisture therein will expand said washer and take up any looseness.

The upper head 6 is of greater width than the lower head 9, and the upper pipe-sections 10 are of greater length than the lower sections 10, the purpose and effect being to permit the lower head to slide up on the rod until the pipe-sections are substantially parallel and vertical, as indicated in Fig. 1.

18 indicates a brass shell which extends from the lower head 9 to the T or branch fitting of the fixture, and this shell contains the gaspipe 19, the rod 8, and a rod 20, which operates the wedge-clamp. These two rods are preferably contained in an inner housing or shell 21, in which the rod 8 fits at a close contact, so that lateral or loose movement is prevented and the parts maintained in proper alinement.

As heretofore stated,the rod 8 works through a hole in. the lower head 9, and located ina recess beside said rod is a wedge 22, the point of which projects upwardly beyond the head, where it is offset, as at 23. A stiff spring 24:

engages under this otfset and tends to lift the wedge and bind the rod against the wall of the hole through which it extends, and thereby hold the parts at the adjustment desired. 'In a recess behind the wedge are a number of balls 25, against which the wedge bears and which facilitate easy operation and prevent sticking of the-wedge. The wedge is connected by the rod 20 to a finger-piece 26 at the lower end, of the rod, said finger-piece being ofltset through a slot 27 in the shell 18 in convenient position for manipulation to raise or lower the chandelier.

A device is illustrated with two folding pipe-sections, one on each side. Obviously one only may be used if the burners can be supplied thereby.

In use to raise or lower the chandelier the finger-piece 26 is pressed down with suflicient force to overcome the spring 24 and disengage the wedge, when the chandelier can be slid up or down on the rod 8 to bring the lights to the height desired. On release of the wedge the spring 24 draws the same up to binding contact with the rod 8, thereby holding the parts set.

The invention will be found useful for all purposes or conditions wherein it is desirable that lights be raised or lowered, and it is to be noticed that there'is no gasway or passage around the rod 8, so that a packed joint around the same is unnecessary.

What I claim as new, and desire to secure by Letters Patent. is-

1. In a chandelier, the combination of upper and lower heads, a rod depending from the upper head and on which the lower head is slidable. means to clamp the latter to the rod at adjustment, a burner-support carried by the lower head, and folding pipe-sections connecting the heads, the upper head being wider than the lower and the upper pipe-section being longer than .the lower, whereby the pipe-sections are foldable to parallelism with the rod.

2. In a chandelier, the combination with a suspension-rod, of a separate head slidable thereon, a gas-pipe and a guide-tube for the rod, depending from the head, a slotted shell inclosing said pipe, tube and rod, and a rod in the shell having at the upper end a wedge engageable between the suspension-rod and head and at the lower end a finger-piece projecting through the slot.

In testimony whereofIhave signed my name to this specification in the presence of two subscribing witnesses. I

GEORGE WHITLOCK POND.
